At different times during the life cycle of a cell, the DNA that makes up the cell's chromosomes can be tightly compacted into a structure that is visible under a microscope, or it can be more ...

Researchers can see this under a microscope, and it’s one of the first signs that a cell might be preparing for programmed DNA elimination. As the cells prepare to divide, the DNA assembles into ...

Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear ... Human chromosomes can be differentiated from one another under a microscope by their lengths and by the ...

During meiosis, the DNA-containing chromosomes can easily be broken ... "You can anesthetize the worm, watch through a microscope, and film the entire process in 45 minutes" as an egg cell ...

A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they ...

Robert Lee Hotz covered new research and its impact on society for The Wall Street Journal.

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

So, it's very easy to see,” she said. To zoom in on changes in chromosome organization during meiosis, the researchers used nuclear membrane and DNA damage protein stains to track nuclear behavior.

Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, chromosomes contain the specific instructions that make each type of living ...
